The fact that the noise is coming out of the lower right speaker
would give someone with knowledge of the signal routing, an idea
of where in the organ the noise originates. If I recall, you've
told us that the volume of the noise varies with the swell pedal,
that tells me that the noise originates inside the organ
somewhere.

Would love to hear it with
the 147. But I don't have one. Got the pedals sounding right
with adjusting the turn screw in the back of the console. Did
notice the lower C spindle was a little worn. As I plunder
along am hoping to stumble upon the "high pitch"which I
believing in a ground problem. It's coming out of the lower
right speaker, if that means anything. It seem also impossible
to get to unless I basically disassemble the lower unit in the
leslie to get to it. Not sure I want to go there.

My comment about the schematics was on
the basis of having an engineer troubleshoot.
Schematics are needed to deal with the issues like
you originally mentioned ..."high pitch".? That is
something you will very likely not be able to "fix"
without someone knowledgeable in electronics.
The schematics are very likely readily
available from this forum, in particular the
resident expert, Chris Clifton.? But this would only
be of any use if you committed to fixing the organ.?
It would be too bad to "return it to the back room
where it was" ....then what?? You
should enjoy it!
The X77 is a powerhouse organ with the
matching Leslie.? I have the luxury of also using
the 147 for the "traditional sound".? It sounds
terrible with both running at the same time. They
each have their purpose.
